Rausu volcano, Japan

Rausu volcano, seen here from the SW at Shiretoko Pass, is a small stratovolcano in NE Hokkaido.

Rausu is located 5 km SW of Shiretoko-Iwo-san volcano along the crest of the elongated NE-trending ridge forming the Shiretoko Peninsula.

Explosive eruptions have taken place several times during the Holocene, including eruptions of pumiceous tephras about 2200 and 1500 years ago.

Recent work has documented a pyroclastic-flow deposit from Rausu that overlies the 1739 tephra from Tarumai volcano.

Rausu is an andesitic-to-dacitic stratovolcano with summit lava domes on the Shiretoko Peninsula in NE Hokkaido.

The 1660-m-high volcano is located along a ridge 5 km SW of Shiretoko-Iwo-san volcano, the NE-most Holocene volcano in Hokkaido.

Young lava flows descent the NW flank and broad areas along the SE flank of Rausu, and an older lava flow traveled about 9 km to the west, reaching the coast of the Sea of Okhotsk along a broad front.

Rausu-dake volcano produced eruptions of pumiceous tephras with associated pyroclastic flows about 2200, 1400, and 800 years ago.

Recent work has documented a pyroclastic-flow deposit that overlies the 1739 tephra from Tarumai volcano in SW Hokkaido.

Stratigraphic relationships place this eruption, the most recent known from Rausu, between about 1750 and 1850 AD.
